Dentists say 12-year-olds in the UK have the best teeth in Europe, but how well do you look after yours? We asked some of you...
10-year-old Abdul said his mum's really strict, so he has to look after his teeth!
Dujonna, 10, said: "I use a pea-sized blob of toothpaste so I don't have too much or too little. I make sure I look after my teeth because if you don't it could cause rotting or tooth decay."
11-year-old Rosa said she tries to brush twice a day, but sometimes she forgets!
"I make sure I brush my teeth every night and every morning, but I hate going to the dentist!" said 11-year-old Samantha.
Georgia, 11, said she always brushes her teeth when she eats sweets and in the evenings - but sometimes she forgets!
"I brush after I have my breakfast and before I go to bed," said 11-year-old Mikey.
